Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic modules, in particular to a photovoltaic panel encapsulation frame and a photovoltaic module. Background Art

[0002] A photovoltaic panel, also known as a solar panel, is the core component of a solar power generation system and is used to directly convert sunlight into electrical energy. The basic component of a photovoltaic panel is a solar cell, usually a photovoltaic cell made of silicon material, and sometimes other semiconductor materials are also used.

[0003] In the prior art, the encapsulation frame of a photovoltaic panel is mainly used to fix the photovoltaic module and provide structural support, and has excellent sealing performance, which not only enhances the overall strength of the photovoltaic module, but also improves its convenience during transportation and installation. However, although the encapsulation frame plays a role in reinforcement, its coverage of the side wall of the photovoltaic panel and the top edge area near the side wall may cause a certain degree of occlusion to the surface of the photovoltaic panel, which not only affects the power generation efficiency of the photovoltaic panel, but also leads to the accumulation of dust on the surface of the photovoltaic panel, thus requiring additional cleaning and maintenance work. Summary of the Utility Model

[0004] In view of this, the utility model provides a photovoltaic panel encapsulation frame and a photovoltaic module to solve the problem of dust accumulation on the surface of the photovoltaic panel.

[0005] In a first aspect, the utility model provides a photovoltaic panel encapsulation frame, comprising:

[0006] A second frame, comprising a second base and a second side sealing plate arranged at an angle to the supporting surface of the second base, and the second side sealing plate is bonded to the side wall of the photovoltaic panel;

[0007] The bonding surface of the second side sealing plate is a rough surface distributed with protrusions, and a receiving groove is formed between any two adjacent protrusions. The receiving groove is adapted to receive bonding glue, and the end of the protrusion abuts against the side wall of the photovoltaic panel, and the ends of all the protrusions are located on the same plane.

[0008] Beneficial effects: When encapsulating the photovoltaic panel with this encapsulation frame, the bottom surface of the photovoltaic panel is set on the supporting surface of the second base, and the photovoltaic panel is supported by the supporting surface. Among them, the second side seal plate of the second frame is bonded to the side wall of the photovoltaic panel to ensure the sealing performance and structural integrity of the photovoltaic panel. Since the second frame only bonds to the side walls in the width direction of the photovoltaic panel, under the action of environmental factors such as external wind or rain, the dust accumulated on the top surface of the photovoltaic panel is likely to flow out from the second frame of the photovoltaic panel, reducing the accumulation of dust on the surface of the photovoltaic panel, reducing the cleaning frequency, improving the maintenance efficiency of the photovoltaic module, and at the same time, the second frame is convenient for processing and easy to form.

[0009] A plurality of protrusions are arranged at intervals on the bonding surface of the second side seal plate, so that a receiving groove is formed between adjacent two protrusions. The existence of the receiving groove allows the adhesive to be distributed under controlled conditions, avoiding the situation of too much or too little adhesive, ensuring the uniform distribution of the colloid, improving the bonding quality and reliability, and at the same time preventing the adhesive from overflowing from the second side seal plate.

[0010] By appropriately filling the adhesive in the receiving groove, the contact area between the second side seal plate and the adhesive can be increased, so that the second side seal plate and the adhesive are mutually embedded, which is beneficial to improving the bonding stability between the second side seal plate and the adhesive, and thus improving the bonding stability between the photovoltaic panel and the frame.

[0011] The ends of the protrusions are located in the same plane, and the ends of the protrusions are abutted against the side wall of the photovoltaic panel, which can enhance the bonding stability and firmness.

[0012] In an optional embodiment, the plane where the ends of all the protrusions are located is parallel to the outer side surface of the second side seal plate.

[0013] Beneficial effects: Setting the plane where the ends of the protrusions are located parallel to the outer side surface makes the second side seal plate as a whole in the shape of a cuboid, which can be simply processed from a cuboid plate, reducing the production cost of the second frame.

[0014] In an optional embodiment, from the bonding surface of the second side seal plate to the outer side surface opposite to the bonding surface, the receiving groove gradually shrinks.

[0015] Beneficial effects: The gradually shrinking design of the receiving groove can guide the adhesive to concentrate on the bonding surface during the curing process, ensuring that the adhesive has sufficient thickness in the key bonding area, thereby improving the bonding strength and sealing performance.

[0016] In an alternative embodiment, the raised portions are strip-shaped, each raised portion is arranged along the extending direction of the second side seal plate, and a plurality of the raised portions are arranged at intervals along the height direction of the second side seal plate. Herein, the height direction may refer to the direction perpendicular to the intersection line of the second side seal plate and the second base within the plane of the second side seal plate.

[0017] Advantageous effects: The strip-shaped raised portions can provide continuous contact points, increasing the contact area with the side wall of the photovoltaic panel, thereby improving the stability and firmness of bonding. Since a plurality of raised portions are arranged at intervals along the height direction of the second side seal plate, a strip-shaped receiving groove is formed between adjacent two raised portions, facilitating the coating of the bonding adhesive in the receiving groove. The strip shape of the raised portions means that the raised portions are ridges, and multiple ridges are distributed parallel or non-parallel to the bonding surface of the second side seal plate, such that any cross-section of the second side seal plate perpendicular to the extending direction of the second frame includes a serrated structure, which is beneficial to enhancing the structural stability of the raised portions themselves and facilitating processing.

[0018] In an alternative embodiment, the cross-section of the raised portion is triangular, trapezoidal or rectangular.

[0019] Advantageous effects: The raised portions arranged in a triangular, trapezoidal or rectangular structure have high stability, can improve the structural strength of the second side seal plate, reduce the risk of deformation in harsh environments, and ensure the long-term stability between the frame and the photovoltaic panel. The triangular, trapezoidal or rectangular structure is simple, and the corresponding raised portions are easy to set corresponding molds and are easy to process. At the same time, setting the raised portions in a triangular shape enables a gradually shrinking receiving groove to be formed between adjacent two raised portions, facilitating the processing of the second side seal plate.

[0020] In an alternative embodiment, an arc chamfer is provided at the end of the raised portion close to the side wall of the photovoltaic panel.

[0021] Advantageous effects: The arc chamfer can smoothly transition the contact between the tip of the raised portion and the side wall of the photovoltaic panel, reduce stress concentration, and prevent damage to the photovoltaic module caused by excessive local stress. During handling and installation, the arc chamfer can reduce the risk of scratching the surface of the photovoltaic panel and protect the integrity of the photovoltaic panel.

[0022] In an alternative embodiment, it further includes:

[0023] A first frame, including a first base and a seal edge plate arranged at an angle to the supporting surface of the first base, the seal edge plate including a first side seal plate and a flanging portion bent from the first side seal plate, the first frame is adapted to be arranged along the length direction of the photovoltaic panel, the first side seal plate is bonded to the side wall of the photovoltaic panel, and the flanging portion is bonded to the top surface of the photovoltaic panel; the second frame is adapted to be arranged along the width direction of the photovoltaic panel;

[0024] A first arc-shaped glue overflow groove is provided at the connection between the first side sealing plate and the first base support surface;

[0025] A second arc-shaped glue overflow groove is provided at the connection between the second side sealing plate and the second base support surface.

[0026] Beneficial effects: When encapsulating the frame of the photovoltaic panel, the first frame is arranged in the length direction of the photovoltaic panel, and the second frame is arranged in the width direction of the photovoltaic panel. The bottom surface of the photovoltaic panel is arranged on the support surfaces of the first base and the second base, and the support surfaces support the photovoltaic panel. Among them, the first side sealing plate of the first frame is bonded to the long side side wall of the photovoltaic panel, and the flanging of the first frame is bonded to the long side top surface of the photovoltaic panel. The second side sealing plate of the second frame is bonded to the short side side wall of the photovoltaic panel. The bonding of the first side sealing plate and the second side sealing plate to the side wall of the photovoltaic panel ensures the sealing performance and structural integrity of the photovoltaic panel. Since the second frame only bonds the side walls in the width direction of the photovoltaic panel, under the action of environmental factors such as external wind force or rain, the dust accumulated on the top surface of the photovoltaic panel is easily discharged outward from the second frame of the photovoltaic panel, reducing the accumulation of dust on the surface of the photovoltaic panel, reducing the cleaning frequency, and improving the maintenance efficiency of the photovoltaic module.

[0027] In summary, the combined use of the first frame and the second frame enhances the overall structural stability of the photovoltaic panel, improves the safety and convenience of the photovoltaic module during transportation and installation, and can effectively prevent the phenomenon of dust accumulation on the surface of the photovoltaic panel.

[0028] The first arc-shaped glue overflow groove can guide the excess adhesive on the first side sealing plate to flow onto the support surface of the first base, promoting the bonding between the bottom of the photovoltaic panel and the first base, ensuring the uniform distribution of the adhesive in the necessary area, and improving the bonding quality.

[0029] The second arc-shaped glue overflow groove can guide the excess adhesive on the second side sealing plate to flow onto the support surface of the second base, promoting the bonding between the bottom of the photovoltaic panel and the second base, ensuring the uniform distribution of the adhesive in the necessary area, and improving the bonding quality.

[0030] In an optional embodiment, a plurality of first glue overflow holes are provided at intervals on the first side sealing plate, and each first glue overflow hole penetrates along the thickness direction of the first side sealing plate;

[0031] A plurality of second glue overflow holes are provided at intervals on the second side sealing plate, and each second glue overflow hole penetrates along the thickness direction of the second side sealing plate.

[0032] And / or, the photovoltaic panel encapsulation frame further includes crossbeams and corner codes. The crossbeams connect two oppositely arranged first frames, and the corner codes connect the adjacent first frame and the second frame. Beneficial effects: During the bonding process, the first glue overflow holes and the second glue overflow holes can collect the glue exceeding the required amount, so that the excess glue overflows from the first glue overflow holes and the second glue overflow holes, preventing it from overflowing to the non-bonding area of the photovoltaic panel, keeping the assembly clean, avoiding the glue contaminating the surface of the photovoltaic panel and affecting the power generation efficiency and aesthetics. At the same time, the design of the glue overflow holes enables the glue to be more deeply embedded in the frame, further enhancing the bonding stability of the glue.

[0033] The crossbeams connect two oppositely arranged first frames, which can significantly enhance the lateral stability of the photovoltaic module. The presence of the crossbeams helps to evenly distribute the load borne by the photovoltaic module, ensuring that when the entire module is subjected to external pressure, each part can share the load evenly and avoid local overload.

[0034] The corner codes are used to connect the adjacent first frame and the second frame to ensure a firm connection between the first frame and the second frame, forming a complete frame structure. The use of corner codes increases the connection strength between the encapsulation frames, improves the rigidity of the entire encapsulation frame, and enables the photovoltaic module to maintain the integrity and stability of the structure when facing harsh environmental conditions.

[0035] In an optional embodiment, the distance between the ends of adjacent protrusions is 0.5 - 1.5 mm;

[0036] And / or, the depth of the receiving groove is 1 - 2 mm;

[0037] And / or, the ends of all protrusions face the second base.

[0038] Beneficial effects: Making the design of the protrusions and the receiving grooves meet the above requirements helps to meet the bonding requirements while saving materials. Setting the ends of each protrusion towards the second base makes the upper surface of the protrusion form an inclined surface that slopes downward. During the installation of the photovoltaic panel, under the guiding action of this inclined surface, it is convenient to place the photovoltaic panel on the second base. Since this inclined surface slopes downward, the protrusion forms a structure similar to a barb, which can effectively prevent the photovoltaic panel from detaching from the second base and ensure that the photovoltaic panel is firmly fixed to the second frame.

[0039] In a second aspect, the present utility model also provides a photovoltaic module, including:

[0040] A photovoltaic panel and at least one photovoltaic panel encapsulation frame.

[0041] Beneficial effects: In this photovoltaic module, since the second frame only bonds the side walls in the width direction of the photovoltaic panel, under the action of environmental factors such as external wind force or rain, the dust accumulated on the top surface of the photovoltaic panel is likely to flow out from the second frame of the photovoltaic panel, reducing the accumulation of dust on the surface of the photovoltaic panel, reducing the cleaning frequency, and improving the maintenance efficiency of the photovoltaic module.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0054] In related technologies, the encapsulation frames of photovoltaic panels are mainly used to fix photovoltaic modules and provide structural support, and have excellent sealing performance. They not only enhance the overall strength of photovoltaic modules but also improve their convenience during transportation and installation. However, although the encapsulation frames play a role in reinforcement, their coverage of the side walls of the photovoltaic panel and the top edge area near the side walls may cause a certain degree of blockage to the surface of the photovoltaic panel, which not only affects the power generation efficiency of the photovoltaic panel but also leads to the accumulation of dust on the surface of the photovoltaic panel, thus requiring additional cleaning and maintenance work.

[0055] To solve the above technical problems, the following will be combined with Figures 1 to 7 , to describe the embodiments of the present utility model.

[0056] According to the embodiments of the present utility model, on the one hand, as Figures 1 to 7 shown, a photovoltaic panel encapsulation frame is provided, including a second frame 3.

[0057] Specifically, as Figure 1 , Figure 4 and Figure 5 shown, the second frame 3 includes a second base 301 and a second side sealing plate 302. The second side sealing plate 302 is disposed at an angle with the support surface of the second base 301, and the second side sealing plate 302 is bonded to the side wall of the photovoltaic panel 2.

[0058] Specifically, as Figure 4 and Figure 5As shown, on the bonding surface 3021 of the second side sealing plate 302, there are a plurality of protruding portions 3022 distributed at intervals. An accommodation groove 3023 is formed between any two adjacent protruding portions 3022. The accommodation groove 3023 is adapted to accommodate bonding glue. The end of the protruding portion 3022 abuts against the side wall of the photovoltaic panel 2, and the ends of the protruding portions 3022 are located in the same plane.

[0059] For this photovoltaic panel encapsulation frame, when encapsulating the photovoltaic panel 2 with the frame, the bottom surface of the photovoltaic panel 2 is arranged on the supporting surface of the second base 301, and the photovoltaic panel 2 is supported by the supporting surface. Among them, the second side sealing plate 302 of the second frame 3 is bonded to the side wall of the photovoltaic panel 2 to ensure the sealing and structural integrity of the photovoltaic panel 2. Since the second frame 3 only bonds the side walls in the width direction of the photovoltaic panel 2, under the action of environmental factors such as external wind force or rain, the dust accumulated on the top surface of the photovoltaic panel 2 is likely to flow out from the second frame 3 of the photovoltaic panel 2, reducing the accumulation of dust on the surface of the photovoltaic panel 2, reducing the cleaning frequency, improving the maintenance efficiency of the photovoltaic module, and at the same time, the second frame 3 is convenient for processing and easy to form.

[0060] A plurality of protruding portions 3022 are arranged at intervals on the bonding surface 3021 of the second side sealing plate 302, so that an accommodation groove 3023 is formed between two adjacent protruding portions 3022. The existence of the accommodation groove 3023 allows the bonding glue to be distributed under controlled conditions, avoiding the situation of too much or too little bonding glue, ensuring the uniform distribution of the glue, and at the same time increasing the contact area between the bonding glue and the second side sealing plate 302, improving the bonding quality and reliability.

[0061] The ends of the protruding portions 3022 are located in the same plane. By arranging the ends of the protruding portions 3022 to abut against the side wall of the photovoltaic panel 2, the stability and firmness of the bonding can be enhanced.

[0062] Specifically, the protruding portion 3022 can be set in any existing shape such as strip shape, block shape, dot shape, etc. Similarly, the shape of the accommodation groove 3023 is determined by the shape of the protruding portion 3022. The accommodation groove 3023 can have various shapes as long as it can ensure that the bonding glue can be accommodated in the accommodation groove 3023.

[0063] Specifically, the plurality of protruding portions 3022 can be arranged at uniform intervals or non-uniform intervals.

[0064] In one embodiment, the plane where all the ends of the protruding portions 3022 are located is parallel to the outer side surface 3024 of the second side sealing plate 302.

[0065] By arranging the plane where the ends of the protruding portions 3022 are located to be parallel to the outer side surface 3024, the second side sealing plate 302 is in an overall cuboid shape and can be simply processed from a cuboid plate, reducing the production cost of the second frame 3.

[0066] In one embodiment, in combination with Figure 4 and Figure 5 as shown, the surface of the second side seal plate 302 opposite to the bonding surface 3021 is the outer side surface 3024, and the accommodating groove 3023 gradually contracts from the bonding surface 3021 of the second side seal plate 302 to the outer side surface 3024.

[0067] The gradually contracting design of the accommodating groove 3023 can guide the bonding adhesive to concentrate towards the bonding surface 3021 during the curing process, ensuring that the bonding adhesive has sufficient thickness in the critical bonding area, thereby improving the bonding strength and sealing performance. As the accommodating groove 3023 gradually contracts, the usage amount of the bonding adhesive can be effectively controlled, avoiding excessive use of the bonding adhesive in non-critical areas, thereby reducing the material cost and weight.

[0068] Specifically, the accommodating groove 3023 can be set as a conical groove, a trapezoidal groove, a triangular groove, etc. In the embodiments of the present application, the shape of the accommodating groove 3023 is not specifically limited.

[0069] In one embodiment, in combination with Figure 4 and Figure 5 as shown, the protruding portion 3022 is set in a long strip shape. Each protruding portion 3022 is arranged along the extending direction of the second side seal plate 302, and a plurality of protruding portions 3022 are arranged at intervals along the height direction of the second side seal plate 302.

[0070] The long strip-shaped protruding portion 3022 can provide continuous contact points, increasing the contact area with the side wall of the photovoltaic panel 2, thereby improving the bonding stability and firmness. Since a plurality of protruding portions 3022 are arranged at intervals along the height direction of the second side seal plate 302, a long strip-shaped accommodating groove 3023 is formed between adjacent two protruding portions 3022, facilitating the coating of the bonding adhesive in the accommodating groove 3023.

[0071] Specifically, the cross-section of the long strip-shaped protruding portion 3022 can be set as a triangle, a square, a rectangle, an arc, etc., or other shapes.

[0072] In one embodiment, as shown in Figure 5 the cross-section of the protruding portion 3022 is triangular, trapezoidal or rectangular.

[0073] The protruding portion 3022 being set in a triangular, trapezoidal or rectangular structure has high stability, can improve the structural strength of the second side seal plate 302, reduce the risk of deformation in harsh environments, and ensure the long-term stability between the frame and the photovoltaic panel 2. At the same time, setting the protruding portion 3022 as a triangle enables a gradually contracting accommodating groove 3023 to be formed between adjacent two protruding portions 3022, facilitating the processing of the second side seal plate 302.

[0074] Specifically, the cross-section of the convex portion 3022 can be set to be a right triangle, an acute triangle, or an obtuse triangle.

[0075] Specifically, the corners of a triangle, trapezoid, or rectangle can be set to corresponding arc chamfers according to requirements.

[0076] In one embodiment, as Figure 5 shown, an arc chamfer 30221 is provided at the end of the convex portion 3022 close to the side wall of the photovoltaic panel 2.

[0077] The arc chamfer 30221 can smoothly transition the contact between the tip of the convex portion 3022 and the side wall of the photovoltaic panel 2, reduce stress concentration, and prevent damage to the photovoltaic module caused by excessive local stress. During processing and installation, the arc chamfer 30221 can reduce the risk of scratching the surface of the photovoltaic panel 2 and protect the integrity of the photovoltaic panel 2.

[0078] Specifically, the radius of curvature of the arc chamfer 30221 can be set as needed, for example, it can be set between 0.01 mm and 0.02 mm.

[0079] Specifically, the depth of the receiving groove 3023 can be set between 0.5 mm and 1.5 mm.

[0080] In one embodiment, as Figures 1 to 3 shown, the first frame 1 includes a first base 101 and an edge sealing plate 102, wherein the edge sealing plate 102 is arranged at an angle with respect to the supporting surface of the first base 101. Figure 2 The holes in are installation vacancies and can be used to fix the corner fitting 5.

[0081] As Figures 1 to 3 shown, the edge sealing plate 102 includes a first side sealing plate 1021 and a flanging 1022, and the flanging 1022 is bent and arranged on the first side sealing plate 1021.

[0082] As Figures 1 to 3 shown, the first frame 1 is adapted to be arranged along the length direction of the photovoltaic panel 2, wherein the first side sealing plate 1021 is bonded to the side wall of the photovoltaic panel 2, and the flanging 1022 is bonded to the top surface of the photovoltaic panel 2.

[0083] As Figure 3 and Figure 4 shown, a first arc-shaped glue overflow groove 103 is provided at the connection between the first side sealing plate 1021 and the supporting surface of the first base 101, and a second arc-shaped glue overflow groove 303 is provided at the connection between the second side sealing plate 302 and the supporting surface of the second base 301.

[0084] When encapsulating the photovoltaic panel 2 with a frame, the first frame 1 is arranged in the length direction of the photovoltaic panel 2, and the second frame 3 is arranged in the width direction of the photovoltaic panel 2. The bottom surface of the photovoltaic panel 2 is placed on the supporting surfaces of the first base 101 and the second base 301, and the photovoltaic panel 2 is supported by the supporting surfaces. Among them, the first side sealing plate 1021 of the first frame 1 is bonded to the long side side wall of the photovoltaic panel 2, and the flanging 1022 of the first frame 1 is bonded to the long side top surface of the photovoltaic panel 2. The second side sealing plate 302 of the second frame 3 is bonded to the short side side wall of the photovoltaic panel 2. The bonding of the first side sealing plate 1021 and the second side sealing plate 302 to the side wall of the photovoltaic panel 2 ensures the sealing and structural integrity of the photovoltaic panel 2. Since the second frame 3 only bonds the side walls in the width direction of the photovoltaic panel 2, under the action of environmental factors such as external wind force or rain, the dust accumulated on the top surface of the photovoltaic panel 2 is likely to flow out from the second frame 3 of the photovoltaic panel 2, reducing the accumulation of dust on the surface of the photovoltaic panel 2, reducing the cleaning frequency, and improving the maintenance efficiency of the photovoltaic module.

[0085] In summary, the combined use of the first frame 1 and the second frame 3 enhances the overall structural stability of the photovoltaic panel 2, improves the safety and convenience of the photovoltaic module during transportation and installation, and can effectively prevent the phenomenon of dust accumulation on the surface of the photovoltaic panel 2.

[0086] The first arc-shaped glue overflow groove 103 can guide the excess adhesive on the first side sealing plate 1021 to flow onto the supporting surface of the first base 101, and can bond the bottom surface of the photovoltaic panel 2 to the first base 101, improving the bonding quality.

[0087] The second arc-shaped glue overflow groove 303 can guide the excess adhesive on the second side sealing plate 302 to flow onto the supporting surface of the second base 301, and can bond the bottom surface of the photovoltaic panel 2 to the second base 301, improving the bonding quality.

[0088] Specifically, the angle between the first base 101 and the edge sealing plate 102 can be set as an acute angle, a right angle or an obtuse angle, etc. Similarly, the angle between the second base 301 and the second side sealing plate 302 can also be set as an acute angle, a right angle or an obtuse angle, etc., and can be adaptively set according to the structure of the photovoltaic panel 2.

[0089] Specifically, the first side sealing plate 1021 and the second side sealing plate 302 can be bonded to the photovoltaic panel 2 with glue, or can be bonded with existing adhesives such as sealant, resin glue, hot melt glue, etc. In the embodiments of the present application, the types of adhesives are not specifically limited.

[0090] Specifically, the supporting surfaces of the first base 101 and the second base 301 can be set as a plane, a curved surface or a wavy surface, etc. In the embodiments of the present application, the structure of the supporting surface is not specifically limited.

[0091] Specifically, a groove 10221 can be provided on one side of the flanging 1022 close to the top surface of the photovoltaic panel 2. The groove 10221 can accommodate an adhesive to ensure firm adhesion between the flanging 1022 and the top surface of the photovoltaic panel 2.

[0092] In one embodiment, as Figure 3 and Figure 5 shown, a plurality of first glue overflow holes 104 are provided on the first side seal plate 1021, and the plurality of first glue overflow holes 104 are arranged at intervals. Each first glue overflow hole 104 penetrates along the thickness direction of the first side seal plate 1021.

[0093] A plurality of second glue overflow holes 304 are provided on the second side seal plate 302, and the plurality of second glue overflow holes 304 are arranged at intervals. Each second glue overflow hole 304 penetrates along the thickness direction of the second side seal plate 302.

[0094] During the bonding process, the first glue overflow holes 104 and the second glue overflow holes 304 can collect the adhesive exceeding the required amount, so that the excess adhesive overflows from the first glue overflow holes 104 and the second glue overflow holes 304, preventing it from overflowing to the non-bonding area of the photovoltaic panel 2, keeping the component clean, and avoiding the adhesive contaminating the surface of the photovoltaic panel 2, which affects the power generation efficiency and aesthetics. At the same time, setting the first glue overflow holes 104 and the second glue overflow holes 304 can increase the contact area between the adhesive and the first frame 1 or the second frame 3, thereby preventing the adhesive from falling off.

[0095] Specifically, the first glue overflow holes 104 and the second glue overflow holes 304 can be provided as circular through holes, square through holes, etc. In the embodiments of the present application, the shapes of the first glue overflow holes 104 and the second glue overflow holes 304 are not specifically limited.

[0096] Specifically, the plurality of first glue overflow holes 104 can be arranged at intervals along the length direction of the first frame 1, and the plurality of second glue overflow holes 304 can be arranged at intervals along the length direction of the second frame 3.

[0097] As Figure 6 and Figure 7 shown, it further includes a cross beam 4 and an angle code 5. The cross beam 4 connects two relatively arranged first frames 1, and the angle code 5 connects the adjacent first frame 1 and the second frame 3.

[0098] The cross beam 4 connecting two relatively arranged first frames 1 can significantly enhance the lateral stability of the photovoltaic module. The presence of the cross beam 4 helps to evenly distribute the load borne by the photovoltaic module, ensuring that when the entire module is subjected to external pressure, each part can share evenly and avoid local overload.

[0099] The corner code 5 is used to connect the adjacent first frame 1 and second frame 3, ensuring a firm connection between the first frame 1 and the second frame 3 and forming a complete frame structure. The use of the corner code 5 increases the connection strength between the encapsulation frames, improves the rigidity of the entire encapsulation frame, and enables the photovoltaic module to maintain the integrity and stability of the structure when facing harsh environmental conditions.

[0100] Specifically, mounting holes can be formed on the side walls of the first frame 1 and the second frame 3. The corner code 5 is fixed to the first frame 1 and the second frame 3 by fasteners passing through the mounting holes. In the embodiments of the present application, the connection method between the corner code 5 and the first frame 1 and the second frame 3 is not specifically limited.

[0101] In one embodiment, the distance between the ends of adjacent protrusions 3022 is 0.5 - 1.5 mm, for example, it can be 0.5 mm, 1 mm, 1.5 mm or other values between any two values. The depth of the receiving groove 3023 is 1 - 2 mm, for example, it can be 1 mm, 1.5 mm, 2 mm or other values between any two values. As Figure 8 shown, the ends of all the protrusions 3022 face the second base 301.

[0102] Setting the ends of each protrusion 3022 to face the direction of the second base 301 makes the upper surface of the protrusion 3022 form an inclined surface that slopes downward. During the installation of the photovoltaic panel, under the guiding action of this inclined surface, it is convenient to place the photovoltaic panel on the second base 301. Since the inclined surface slopes downward, the protrusion 3022 forms a structure similar to a barb, which can effectively prevent the photovoltaic panel 2 from detaching from the second base 301 and ensure that the photovoltaic panel 2 is firmly fixed to the second frame 3.

[0103] The installation process of the photovoltaic panel encapsulation frame in this embodiment is described as follows:

[0104] Apply an appropriate amount of adhesive to the bonding surface 3021 of the second side seal plate 302. Set the supporting surface of the second frame 3 on the bottom surface of the photovoltaic panel 2, so that the second side seal plate 302 is bonded to the short side side wall of the photovoltaic panel 2. During the extrusion of the second side seal plate 302, the excess adhesive will flow to the supporting surface of the second base 301 through the second arc-shaped adhesive overflow groove 303, so that the supporting surface of the second base 301 is bonded to the bottom surface of the photovoltaic panel 2. In the same way, bond the first frame 1 to the long side of the photovoltaic panel 2, fix the two relatively arranged first frames 1 through the cross beam 4, and fix the adjacent first frame 1 and second frame 3 through the corner code 5.

[0105] According to the embodiments of the present invention, on the other hand, as Figures 1 to 7As shown, a photovoltaic module is also provided, which includes a photovoltaic panel 2 and a photovoltaic panel encapsulation frame.

[0106] Specifically, there is at least one photovoltaic panel 2.

[0107] Specifically, the first frame 1 is arranged on the side wall of the photovoltaic panel 2 along the length direction of the photovoltaic panel 2, and the second frame 3 is arranged on the side wall of the photovoltaic panel 2 along the width direction of the photovoltaic panel 2.

[0108] In this photovoltaic module, since the second frame 3 only bonds the side walls in the width direction of the photovoltaic panel 2, under the action of environmental factors such as external wind force or rain, the dust accumulated on the top surface of the photovoltaic panel 2 is likely to flow out from the second frame 3 of the photovoltaic panel 2, reducing the accumulation of dust on the surface of the photovoltaic panel 2, reducing the cleaning frequency, and improving the maintenance efficiency of the photovoltaic module.

[0109] Specifically, one or more photovoltaic panels 2 can be provided. In the embodiments of the present application, the number of photovoltaic panels 2 is not specifically limited.

[0110] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
